/dev/sda1 disk full - 100% usage

Question

My Ubuntu 16.04 system's boot partition is completely full, and I have had problems trying to get it fixed.

$ df -h
udev                        2,9G       0  2,9G    0% /dev
tmpfs                       597M     63M  535M   11% /run

tmpfs                       597M       0  597M    0% /run/user/1000

I tried to do sudo apt-get autoremove but that fails:

Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 linux-image-extra-4.4.0-96-generic : Depends: linux-image-4.4.0-96-generic but it is not installed
 linux-image-generic : Depends: linux-image-4.4.0-96-generic but it is not installed
                       Recommends: thermald but it is not installed
 E: Unmet dependencies. Try using -f.

Using -f runs me into the error that there is no space left...

Maybe this information is needed:

The purge-old-kernels (/usr/bin/purge-old-kernels) script from the byobu package will clean that right up, politely (keeping the package management system happy). If you don't have byobu installed, let me know and I'll post the script. DO NOT Manually delete stuff. — waltinator, Sep 24 '17 at 14:32
